Most provider markets (especially hospitals) are also highly concentrated—roughly 80%, according to criteria established by the FTC and Department of Justice[118]—so insurers usually have little choice about which providers to include in their networks, and consequently little leverage to control the prices they pay. Large insurers frequently negotiate most-favored nation clauses with providers, agreeing to raise rates significantly while guaranteeing that providers will charge other insurers higher rates.[119]

^ e.g. House Bill H.R.3962 Section 322 (b)2(B) "AMORTIZATION OF START-UP FUNDING- The Secretary shall provide for the repayment of the startup funding provided under subparagraph (A) to the Treasury in an amortized manner over the 10-year period beginning with Y1". The Senate HLP Committee bill contains a similar clause in § 3106 "A Health Benefit Plan Start-up Fund will be created to provide loans for initial operations, which the plan will be required to pay back no later than 10 years after the payment is made."

The Blue Cross Blue Shield Association (BCBSA) is a federation of 38 separate health insurance organizations and companies in the United States. Combined, they directly or indirectly provide health insurance to over 100 million Americans.[92] BCBSA insurance companies are franchisees, independent of the association (and traditionally each other), offering insurance plans within defined regions under one or both of the association's brands. Blue Cross Blue Shield insurers offer some form of health insurance coverage in every U.S. state, and also act as administrators of Medicare in many states or regions of the United States, and provide coverage to state government employees as well as to federal government employees under a nationwide option of the Federal Employees Health Benefit Plan.[93]
Shortly after his inauguration, President Clinton offered a new proposal for a universal health insurance system. Like Nixon's plan, Clinton's relied on mandates, both for individuals and for insurers, along with subsidies for people who could not afford insurance. The bill would have also created "health-purchasing alliances" to pool risk among multiple businesses and large groups of individuals. The plan was staunchly opposed by the insurance industry and employers' groups and received only mild support from liberal groups, particularly unions, which preferred a single payer system. Ultimately it failed after the Republican takeover of Congress in 1994.[34]
As the population covered by Medicare grows, its costs are projected to rise from slightly over 3 percent of GDP to over 6 percent, contributing substantially to the federal budget deficit.[47] In 2011, Medicare was the primary payer for an estimated 15.3 million inpatient stays, representing 47.2 percent ($182.7 billion) of total aggregate inpatient hospital costs in the United States.[12] The Affordable Care Act took some steps to reduce Medicare spending, and various other proposals are circulating to reduce it further.
While politically difficult, some politicians and observers have argued for a single-payer system.[30] A bill, the United States National Health Care Act, was first proposed by Representative John Conyers in 2003[31] and has been perennially proposed since, including during the debate on the public option and the Patient Protection and Affordable Care Act.[32] President Obama has come out against a single-payer reform at this time, stating in the joint session of Congress that "it makes more sense to build on what works and fix what doesn't, rather than try to build an entirely new system from scratch."[33] Obama had previously expressed that he is a proponent of a single payer universal health care program during an AFL-CIO conference in 2003.[34]
In 2006, a new system of health insurance came into force in the Netherlands. This new system avoids the two pitfalls of adverse selection and moral hazard associated with traditional forms of health insurance by using a combination of regulation and an insurance equalization pool. Moral hazard is avoided by mandating that insurance companies provide at least one policy which meets a government set minimum standard level of coverage, and all adult residents are obliged by law to purchase this coverage from an insurance company of their choice. All insurance companies receive funds from the equalization pool to help cover the cost of this government-mandated coverage. This pool is run by a regulator which collects salary-based contributions from employers, which make up about 50% of all health care funding, and funding from the government to cover people who cannot afford health care, which makes up an additional 5%.[31]

Health insurance in the United States is any program that helps pay for medical expenses, whether through privately purchased insurance, social insurance, or a social welfare program funded by the government.[1] Synonyms for this usage include "health coverage", "health care coverage", and "health benefits". In a more technical sense, the term "health insurance" is used to describe any form of insurance providing protection against the costs of medical services. This usage includes private insurance and social insurance programs such as Medicare, which pools resources and spreads the financial risk associated with major medical expenses across the entire population to protect everyone, as well as social welfare programs like Medicaid and the Children's Health Insurance Program, which both provide assistance to people who cannot afford health coverage.
